1. An imaging device comprising:
- a first microlens having a first lens layer and a second lens layer disposed above the first lens layer;
a second microlens disposed adjacent to the first microlens having a third lens layer and a forth lens layer disposed above the third lens layer; and
an inter-pixel gap disposed between the first microlens and the second microlens,whereinthe first lens layer, the second lens layer, the third lens layer and the fourth lens layer each have a thickness greater than zero throughout the inter-pixel gap,a periphery of the first microlens is disposed between the inter-pixel gap and a center portion of the first microlens,a periphery of the second microlens is disposed between the inter-pixel gap and a center portion of the second microlens,a thickness of the second lens layer at the center portion of the first microlens is less than a thickness of the second lens layer at the periphery of the first microlens, anda thickness of the fourth lens layer at the center portion of the second microlens is less than a thickness of the forth lens layer at the periphery of the second microlens.

Abstract
A solid-state imaging device includes: a first lens layer; and a second lens layer, wherein the second lens layer is formed at least at a periphery of each first microlens formed based on the first lens layer, and the second lens layer present at a central portion of each of the first microlenses is thinner than the second lens layer present at the periphery of the first microlens or no second lens layer is present at the central portion of each of the first microlenses.
